A North American railroad yard in Fort Worth, Texas, has upgraded their current Domain Operations Controller System to include RailComm's Blue Flag Indicator (BFI) System within their facility.

The RailComm BFI System allows a user to apply blue flag protection to the trim yard and control 14 derails on seven different tracks. The BFIs are positioned in pairs at different locations along the track.

RailComm's 2.4 GHz RADiANT spread spectrum data radios are used to provide communication between the field and control locations.
